Conservation Management Actions (CMAs)

Species: California leaf-nosed bat (Macrotus californicus)

In the Reserve Design
BLM LUPA Lands:

AM-RES-BLM-1: The following CMA will be implemented on BLM LUPA conservation designations for all natural communities and Covered Species: The values, goals, objectives, and management actions established in the BLM special land allocation management plans (i.e., NLCS, ACEC and wildlife allocation) apply to land with BLM LUPA conservation designations, as described in Appendix L. Natural communities and Covered Species within BLM LUPA conservation designations will be managed according to the unit-­-specific management actions to maintain the vegetation, fish and wildlife, and other resource values within the NLCS/ACEC/Wildlife Allocation unit as described in the BLM special land allocation management plans (Appendix L).

Species: Desert bighorn sheep (Ovis canadensis nelsoni)

In the Reserve Design
BLM LUPA Lands:

AM-RES-BLM-1: The following CMA will be implemented on BLM LUPA conservation designations for all natural communities and Covered Species: The values, goals, objectives, and management actions established in the BLM special land allocation management plans (i.e., NLCS, ACEC and wildlife allocation) apply to land with BLM LUPA conservation designations, as described in Appendix L. Natural communities and Covered Species within BLM LUPA conservation designations will be managed according to the unit-­-specific management actions to maintain the vegetation, fish and wildlife, and other resource values within the NLCS/ACEC/Wildlife Allocation unit as described in the BLM special land allocation management plans (Appendix L).

AM-RES-BLM-ICS-10: Significant new ground disturbance, excluding transmission projects in designated and new utility corridors, will not negatively affect access and use to known or potential water sources used by bighorn sheep.

AM-RES-BLM-ICS-11: BLM designated routes will be appropriately signed to limit use to the roads and trails, if necessary to reduce impacts from the recreational use to lambing and rearing.

  • Rock climbing restrictions during the peak lambing and rearing season (March 1 through May 31) on BLM-administered lands will be considered if data indicates likely disturbance to lambing and rearing in occupied sheep core locations.
  • AM-RES-BLM-ICS-12: BLM designated routes will be appropriately signed to limit use to the roads and trails, if necessary to reduce impacts from the recreational use to lambing and rearing.

  • For non-BLM Lessee’s, domestic livestock will not be allowed to be trailed (transported on foot (herded)) through known or likely to be occupied bighorn sheep habitat, to minimize exposure and disease transmission to bighorn sheep. Vehicular movement of livestock will be allowable. Livestock will not be allowed to exit the vehicle transport, except in emergencies, while on BLM- administered land.
  • For BLM Lessee’s, consistent with existing (at time of ROD) leases and allotment plans, domestic livestock will be controlled and moved to minimize exposure and disease transmission to bighorn sheep, using techniques including but not limited to fencing with adequate buffers, vehicle transport, and timing. Vehicular movement of livestock will be allowable. Livestock will remain in the vehicle transport, except in emergencies, while on BLM-administered land, unless at the destination.
  • For BLM grazing Lessee’s, trailing of domestic sheep between discontiguous allotments, may be permittable if done in a manner, including timing, which prevents interaction with bighorn sheep and avoids disease transmission from domestic sheep to bighorn sheep.
  • At the time of grazing allotment lease and/or allotment plan renewal, a measure to eliminate trailing within allotments (movement of domestic livestock on foot or herding) through known or likely to be occupied bighorn sheep habitat will be considered and analyzed using the best available science on domestic livestock disease transmission to bighorn sheep.
  • Rock climbing restrictions during the peak lambing and rearing season (March 1 through May 31) on BLM-administered lands will be considered if data indicates likely disturbance to lambing and rearing in occupied sheep core locations.
  • AM-RES-BLM-ICS-13: To reduce the impact on bighorn sheep from domestic livestock in grazing allotments, BLM proposes:

  • Permanently closing specified vacant allotments
  • Accepting voluntarily retirement of allotments
  • Accepting donation of allotments as one component of mitigation
  • Requiring specific terms and conditions in renewed grazing permits, as needed
  • Considering converting domestic sheep allotments to cattle allotments.
  • Consistent with existing or renewed grazing allotment plans, remove or alter livestock fencing to enhance bighorn sheep movements.
  • Species: Desert tortoise (Gopherus agassizii)

    In the Reserve Design
    BLM LUPA Lands:

    AM-RES-BLM-1: The following CMA will be implemented on BLM LUPA conservation designations for all natural communities and Covered Species: The values, goals, objectives, and management actions established in the BLM special land allocation management plans (i.e., NLCS, ACEC and wildlife allocation) apply to land with BLM LUPA conservation designations, as described in Appendix L. Natural communities and Covered Species within BLM LUPA conservation designations will be managed according to the unit-­-specific management actions to maintain the vegetation, fish and wildlife, and other resource values within the NLCS/ACEC/Wildlife Allocation unit as described in the BLM special land allocation management plans (Appendix L).

    AM-RES-BLM-ICS-1: Any area that has been or will be identified as a Tortoise Translocation Area, as part of the fulfillment of an ESA section 7 Biological Opinion, will be identified as a development avoidance area. No development that requires translocation of tortoises, will be authorized within these areas and they will be managed for the conservation of desert tortoise.

    AM-RES-BLM-ICS-2: Covered Activities, except transmission projects, that will result in the long-term removal of habitat supporting an adult desert tortoise density (i.e., individuals 160mm or more) of more than 5 per square mile or more than 35 individuals total are prohibited. The number of desert tortoises on-site will be based on estimates derived from the protocol surveys described in AM-DFA-ICS-3 using the USFWS’s pre-project survey protocol.

    AM-RES-BLM-ICS-3: Covered Activities, except transmission projects, in desert tortoise TCAs or linkages that will result in long-term removal of habitat supporting more than 5 adult individuals are prohibited. The number of desert tortoises on-site is based on estimates derived from the protocol surveys described in AM-DFA-ICS-3 using the USFWS’s pre-project survey protocol.

    AM-RES-BLM-ICS-4: Covered Activities will not exceed the long-term ground disturbance cap (see "BLM disturbance cap" in the Glossary of Terms) shown below in Table II.3-14 for portions of the BLM LUPA conservation designations that are required for desert tortoise conservation.

    1 Tortoise Conservation Areas are shown in Appendix H.
    2 All disturbance thresholds identified for a given TCA, desert tortoise linkage, or other portion of the desert tortoise reserve are allocated proportionally to each jurisdiction managing land within that geographic area. For example if 100 acres is the allowable disturbance within a given TCA’s boundary and the BLM administers 99% of the land within that TCA, the BLM’s allotted disturbance level will be 99 acres and the remaining disturbance will be proportionally divided among the other jurisdictions (i.e., County, City, State, etc.) within that unit.

    AM-RES-BLM-ICS-5: A Designated Biologist (see Glossary of Terms) will accompany any geotechnical testing equipement to ensure no tortoises are killed and no burrows are crushed.

    AM-RES-BLM-ICS-6: New roads will undergo a route designation process, and for BLM-administered lands designated through a Travel and Transportation Management Plan within BLM LUPA conservation designations.
